RTCP XR capture and Fix for Time stamp value 0

Build Information:
Paste the COMPLETE build information from "Help->About Wireshark", "wireshark
-v", or "tshark -v".
1. packet receipt times report is always showing value 0
2. Sequence Number is not according to the Thinning Value. 
Ex: If thinning value is 3 report for every 8th packet but wireshark showing
every sequence number .

>From RFC 3611, Thinning Value:
A thinning value, T, selects a subset of packets within the sequence
number space: those with sequence numbers that are multiples of 2^T.
Packet reception and loss reports apply only to those packets.  T can
vary between 0 and 15.  If T is zero, then every packet in the
sequence number space is reported upon.  If T is fifteen, then one in
every 32,768 packets is reported upon. 

Attached capture and fix for 1(time-stamp value 0)
